The MB contains a third TTY port (TTY2), which is reserved for XSM connection. The DB TTY2
is not used.
LED indicators
The faceplate Ethernet port contains LED indicators incorporated into and RJ45 connector.
The Embedded Ethernet Switch directly controls the faceplate Ethernet port.
The backplane TLAN/ELAN ports' RJ45 connectors are installed on Backplane . The LED
indicators contain the same signal assignment as faceplate RJ45 connectors.
Table 255: Ethernet LED indicator functions
on page 604 summarizes the Ethernet LED

When a link is establish, the green LED illuminates and flashes when activity exists on the link.
When the link is established at a 100 BaseT speed, the yellow LED illuminates, otherwise it
does not illuminate.
Network connections and dual homing
Each of the dual assembly boards of the MG XPEC contains 4 physical network connections.
The MG XPEC contains no physical network back plane connection as does the MGC. The
dual homing feature on the MGX works identically to the MGC, except all 4 network connection
are on the faceplate. Faceplate connections must be routed to the rear I/O using the new
NTDW25AAE6 cable kit. See
on page 605 for the MG XPEC
faceplate.
